Active clinical trials for "Malocclusion"

This study will collect data to try to assess which one of the two management options works better. The first option involves the use of the bite corrector first and then braces, while the second option involves the temporary addition of small support bone screws with the bite corrector later and then braces. Currently, it is not clearly known if there are important differences between the proposed management options. Such approaches are conventionally used in orthodontic practices. The information collected in this study will be used to compare the differences in the nature of the facial, teeth, and bone changes after the treatment. Questions about the experience while using the devices will be asked.

Patient with class ii division 1 malocclusion who have mild increased overjet will be treated in this study. The efficacy of clear aligners in the treatment of Class II division 1 Malocclusion Using Intermaxillary Elastics will be assessed. The skeletal, dental and soft tissues changes resulted by this intervention will be studied and compared with the results of Traditional treatment with fixed appliances. There are two group: a group of patients in which participants will be undergo to the clear aligners with class ii elastics. a group of patients in which participants will be undergo to the traditional fixed appliances with class ii elastics.

Effects of modified fixed twin block versus removable twin block on skeletal class 2 growing patients with mandibular deficiency: A Randomized Clinical Trial

study will be directed to evaluate the effect of low-level laser therapy during maxillary molar distalization using a skeletally anchored appliance

There's a scarcity in literature concerning the comparison of the effectiveness of brackets in its torque and tip ability, the time takes for leveling and alignment comparing between different orthodontic bracket brands, and its effect on the rate of tooth movement. The purpose of this study is to determine, In orthodontic patients with Class I molar relation and teeth crowding, in which different bracket brands will be compared.

The aim of this longitudinal randomized investigation is to determine the long-term effects of early lateral crossbite correction with Quad-Helix appliance, during the deciduous dentition, on craniofacial structures and dental arches, compared to treatment started later, after the first permanent molars have erupted. The hypothesis is that the timing of treatment has significant effects on orthodontic treatment total time, the general outcome of the treatment, and the compliance of the patient. The Age cohort of five-year-old of children living in the community areas of Oulunsalo are screened at the age of 5 years for malocclusions. Of these children 80 children who meet the criteria are chosen for the study after the written consent. The children are randomized into two groups. In the first group the treatment with Quad-Helix appliance is started at the age of 5 to 6 years, before the eruption of the permanent molars. The device is cemented to the second deciduous molars. The treatment is continued and continued until normal lateral occlusion is achieved and the device is kept stable for one year after this. In the second group headgear treatment is started after the first permanent maxillary molars have erupted. The device is cemented to the first permanent molars. The treatment is continued until normal lateral occlusion is achieved and the device is kept stable for one year after this. In both groups dental casts, cephalograms, and standardized 3D facial photographs are taken before treatment (T0), after the first treatment phase (T1), after the second treatment phase (T2) and after the growth (T3). Facial 3D scanning is performed for all the subjects after the treatment to find out the effect of different treatment methods on facial characteristics. The dental casts are scanned to make 3D models of the cast to be used in detailed analysis. A wide multi-level questionnaire is performed before, during and after the study to the parents and the children to find out the comprehensive effects of orthodontic treatment on the well-being of the child. The questionnaire includes the Rutter's child behavioural pattern (Rutter et al., 2001). In both studies, all the guidelines of RCT are applied. Blinding of the clinicians is gained, as the orthodontists or dentists treating the children are not aware of the rationale of the study. Blinding is applied on all measurement of the documents.

Class II malocclusion with excessive overjet is one of the most common malocclusions among children and adolescents. The overall goal of the project is to analyze orthodontic treatment of Class II malocclusion with excessive overjet when the treatment is started in different ages and treated with removable and/or fixed appliance. Treatment initiated before the age of eleven is performed with a removable functional appliance, Headgear Activator (HGA). Treatment starting in early adolescence is performed with fixed orthodontic appliance (FA). The hypotheses are: Treatment with HGA at the age of nine or eleven is effective. No spontaneous correction of the malocclusion is expected in the untreated control group. Patient experience, treatment effect and cost-effectiveness are equivalent whether the treatment with HGA is initiated at the age of nine or eleven. Treatment results, patient experience and treatment- and cost-effectiveness are equivalent whether treatment is initiated early with HGA or initiated in early adolescence with FA. The treatment of Class II malocclusion with excessive overjet renders long-term treatment stability and patient satisfaction.

The goal of this clinical trial is to compare the pharyngeal airway changes after treatment with Myobrace and after treatment with Twinblock in developing skeletal Class II patients. The main question it aims to answer is: Is the efficacy of the twin-block Vs Myobrace appliances in the improvement of pharyngeal airway dimensions in adolescents having skeletal Class II malocclusion with retrognathic mandible utilizing sagittal pharyngeal airway area measurements.

Rapid palatal expansion aims at skeletally correcting the transverse maxillary deficiency by applying forces to separate the mid-palatal suture. In adult patients, the separation of the mid-palatal suture may not be possible due to its increased interdigitation. Miniscrew-assisted rapid maxillary expansion (MARPE) was proposed to transmit the forces directly to the mid-palatal suture through palatal miniscrews in addition to the anchor teeth. However, some non-growing patients may not respond favorably to MARPE. Hence, the use of corticopunctures as an adjunct to MARPE was recently proposed to overcome the increased resistance of the sutures in adult patients. The study aims to assess and compare the skeletal and dental effects of miniscrew-assisted rapid palatal expansion with and without corticopunctures in non-growing patients.

The decision on aligner changing is based on orthodontists' personal experience and common knowledge that an approximated time span for the aligner have exhausted its biological efficacy. However, a one size fits all approach is not always ideal, as an average determined time is not taken into account of a patient's individual biological response. The aligners could be progressed earlier than the determined time, or they may stay inactive for a while, waiting for the in-office visit. Dental MonitoringTM is the only available technology that provides 3D monitoring of teeth movement, reconstructs 3D digital models remotely, and auto-detect clinical situations by their patented AI algorithms. The investigators have reported high accuracy of DMTM to monitor the tooth movement in vitro. However, the efficacy of DMTM on orthodontic treatment and the accuracy of DMTM in the orthodontic patients has not been investigated yet. In this proposal, the investigators are implementing the Dental MonitoringTM application and 3D tracking of tooth movement powered by AI algorisms as a novel tool to customize aligner changing intervals. The ultimate goal is to reduce in-office visits and treatment duration while maintaining regular monitoring, thus not jeopardizing expected results. It is imperative to investigate the Teledentistry for its effectiveness, reliability, ease of use, patient satisfaction, and value on the overall health and oral health system, especially as a critical tool during public health emergency situations.
